Socio-economic activities in the present world have become increasingly interdependent because of rapid technological progress, urbanization, and globalization. Because of these interdependencies between human society and natural ecosystems, climate impacts on one sector may influence other sectors, including seemingly remote ones, which we call “interconnections of climate risks”. While a substantial number of climate risks are identified in the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5), there have been few attempts to explore the interconnections between them in a comprehensive way.
